Check the electrical connectors and check the wiring.
Bodily contact with electrical potential can cause bodily injury or death.To avoid the possibility of injury or death, ensure that the main power supply has been disconnected before performing any maintenance or removing any modules.
Disconnect the power supply.
Check the electrical connectors and check the wiring for damage or bad connections.
Verify that all modules are properly seated.
Verify the status of the LED on the SLC 5/04.The results of the preceding procedure are in the following list:
All of the components are fully installed. All of the components are free of corrosion. All of the components are free of damage. All of the modules are properly seated. Proceed to 2.
The components are not fully installed. The components are not free of corrosion. The components are damaged. All of the modules are not properly seated. Repair the component. Verify that the repair resolves the problem. STOP.
Check for drift.
Apply pressure or apply temperature. Determine when the contact closes.
Measure the continuity between the common terminal and the normally open terminal. Determine when the contact closes.The results of the preceding procedure are in the following list:
The contact closes when the contact is actuated. Proceed to 3.
The contact does not close when the contact is actuated. Replace the contactor. Verify that the repair resolves the problem. Stop.
Check the contactor for chatter.
Verify that the contactor is adjusted to the original setpoint.The results of the preceding procedure are in the following list:
The contactor does not cycle frequently. Stop.
The contactor cycles frequently. Replace the contactor. Verify that the repair resolves the problem. Stop.
